5.6 Input Menu Selections
The Input Menu selections are depend-
ent on whether the unit is set for Analog
or Digital modulation (Section 5.2).
Only one input can be made active at a
time. The Input Menu controls the ac-
tive input, regardless of any signals pre-
sent on the input connectors.
When digital modulation is selected,
the available input selections are:
Composite - The signal is converted
to digital via the MPEG Encoder and
routed to the digital modulator.
SDI - The signal routes through the
MPEG Encoder and then to the digital
modulator.
External 70 MHz Digital - This input
bypasses the encoder and modulator,
and routes to the heterodyne up-
converter.
ASI - Input bypasses the Encoder
and goes to the digital modulator.
(The ASI rate must be at or below the
maximum digital modulation rate.)
Firewire – The MPEG2 data is
extracted and sent to the digital
modulator.
